SPECIFICATION forming part of Letters Patent No. 459,927, datedSeptember 22, 1891.

Application filed January 12, 1891- Serial No. 377,554. (No modal.)Patented in Germany June 12, 1890, No. 54,595 in France August 6.1890,110. 194,302,3J1dl11 Belgium August '7, 1890, No. 91,543.

To all whom it may concern:

Be it known that I, GEORGE WILLIAM BEN- JAMIN CREEs, a subject of theQueen of Great Britain, residing in Wingfield, near Trowbridge, in thecounty of \Viltshire, England, have invented certain newand usefulImprovements in Machinery for \Vashing Plates, Dishes, and the Like,(for which I have obtained Letters Patent in the following countries: inGermany, No. 54,595, dated June 12, 1890; in France, No. 194,302, August6, 1890, and in Belgium, No. 91,5l3, dated August 7, 1890,) of which thefollowing is a specification.

This invention has for its object the construction of a simple,effective, and economically-built machine for washing plates, dishes,and similar articles, and suitable either for domestic use or forhotels, restaurants, steamships, or any establishment requiring tocleanse a large number of plates, dishes, and the like within a shortperiod of time.

In carrying out my invention I provide a box, trough, crate,or othersimilar receptacle, preferably rectangular in shape, in which is mountedin suitable bearin gs a block or roller round which I spirally attachsections of wood or other suitable material, carrying brushes or othercleansing agents fixed or fitted therein or thereon in the form of ascrew, and between these convolutions I cut or form a groove or notch inthe block or barrel. The block carrying the brushes or other cleansingagents is revolved by suitable mechanism, and I prefer to use anarrangement of chainwheel gearing actuated by a fly-wheel, handle,treadle, or other device. At one side of the box, frame-Work, orreceptacle I mount one or more screw or worm rollers, plain rollers, orendless bands, also actuated by the chain gearing or other device fortransmitting motive power and arranged to run at such a speed as willinsure the proper revolution of the plate or other article placed in themachine.

Referring to the accompanying sheet of drawings, and to the letters ofreference marked thereon, Figure 1 is a sectional elevation showing theapparatus fitted in a box or tank capable of holding water or otherfluid and actuated by gearing worked by ahandle.

Fig. 2 is an end elevation of the box or tank, showing a suitablegearing for actuating the machine. Fig. 3 is a detail view of onesection of the brush-back, showing a method of attaching the same to theblock or barrel.

Fig. 4 is an enlarged view of the delivery end of the block-shaft orbarrel, showing a plate being ejected from the machine.

Similar letters of reference indicate corresponding parts.

In the drawings a box or tank is shown capable of holding fluids; butthe apparatus may be fitted to an open-chamber frame-work or crate ofany suitable material, so that it may be placed in a larger receptaclecontaining fluid andremoved therefrom at will, if found desirable, thefluid being free to circulate between and around the brushes.

In the machinehere representedAis abox, tank, or receptacle havingmounted therein on bearings B B a central stock, shaft, or barrel 0, inwhich is cut a spiral groove D. Upon and around the barrel 0, I attachsections such as E, Fig. 3, on which, at one end or both sides, arefitted bristles or other cleansing agent. These sections are jointed andfitted to each other and to the block or barrel 0 in such a manner as toform a worm or screw, and the brushes, &c are sufficiently long toembrace and thoroughly cleanse any article lying between them.

In Fig. 3 I show a convenient form of a section of brush-back, (withoutthe bristles,) as above described, and a metal band H is attached to theunder side and shaped at either end to engage with the last andfollowing section until the worm or spiral is completed, the endsections being screwed or otherwise secured to the barrel or block. Theends of the sections are also mortised to fit studs upon the barrel.

At convenient points in the back of the receptacle I mount other plainor worm rollers J K, revolving in bearings J J 2 K K and actuated bysprocket-wheels L M and the chain gearing shown in Fig. 2. On thefiy-wheel N, Fig. 2, being turned, the endless chain 0, passing over theteeth of wheel P, sets in motion the barrel or stock 0, and at the sametime the rollers J K are revolved. A plate or dish being placed at anypoint between the brushes and with its edge in the spiral groove I), theupper portion of the edge rests against rollers J or K, according to itssize, and the apparatus, being in motion, is propelled along the spiralgroove D and between the brushes until it arrives at or near Q, Fig. 1,when, the groove running out, it rises to the face of the block orbarrel and onto a block or cam which is fixed thereon for the purpose ofraising the plate or other article clear of the brushes, and it thenassumes the position shown byi/cin Fig. at and falls upon the tiltingboard or platform R, which is controlled by a cord, chain, or spring S,passing over a pulley T and regulated by a balance-weight U; or anyother device may be employed. The platform R is made to assume theposition shown in Fig. 4 by means of a cam \V, attached to the end ofthe block or barrel C. The plate or article falling upon the tiltingplatform is projected into a tank or other receptacle containing,

preferably, hot or cold fluid for rinsing purposes, and it is noweffectually cleansed and may be taken out by hand and stacked fordrying.

Having thus described my invention, I claim as new and desire to secureby Letters Iatent 1. In a dish-washing machine, the combination, with arotative shaft having spirallyarranged brushes or wipers, of means forguiding plates between said brushes or wipers, substantially as setforth.

2. In a dish-washing machine, the combination, with a rotative shafthaving spirallyarranged. brushes or wipers, of a spirallygrooved shaftfor guiding plates between said brushes or wipers, substantially as setforth.

3. In a dish-washing machine, the combination, with a rotative shafthaving spirallyarranged brushes or Wipers, of means for guiding platesbetween said brushes or wipers, and a tilting platform at one end ofsaid shaft, substantially as herein shown and described.

4. In a dish-washing machine, the combination, with a rotative shafthaving spirallyarranged brushes or wipers, of means for gu iding platesbetween said brushes or wipers, a tilting platform atone end of theshaft, and a cam projection on the end of said shaft adapted to act onthe said platform, substantially as set forth.

5. In a dish-washing machine, the combi nation, with a rotative shaftbearing spirally arranged brushes or wipers, of a spirallygroovedshaftfor guiding plates between said brushes or wipers, and means forrotating both shafts simultaneously, substantially as set forth.

6. In a dish-washing machine, the combination, with a shaft, of a seriesof sections E, secured thereon to form a spiral rib, and brushes orwipers on said sections, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
